FLANGING SPECIFICATION forming part of`Lette1s IVIACHINE.

Patent No. 291,620, dated January e, 1824.

Application tiled February 5, 1853. `(No model.)

Be it known that I, Riel-IARD C. NUGENT, acitizen of the United States, residing at Pitts` burg, in the county o'fAllegheny and State of Pennsylvania, have invented certain new and useful Improvements in Machanes for Flanging Metal Plates of Regular or Irregular Form, of which the following is a i'ull, clear, and

exa-ct description.

Fig. 2, a detail view ol the segmental rollerbearing rack; Fig. 3, a side elevation ot' one ofthe segmental arms; 4t, a detail plan view of the large gear-wheel and its arms; Fig. 5, detail views of pattern-forms of different outlines.

l Similar letters oi' reference indicate corresponding parts throughout the various views.

A represents the bed-plate of the machine,

near the periphery of which are secured the lowerextremities of three curved housings, B. The upper ends of these housings are fast in the annular nut O.

To the center of the bedplate A is bolted the pillar D, which has secured to its top the table E, the latter carrying the metal plate while being ilanged.` Said plate is held rigidly in place by the "clamp-plate F, which is borne by a screw, G, passing through the aforesaid annular nut O. lIhe free end of the screw is provided with alhandavheel or other like device, by turning which the clamp-plate F is raised or lowered.

Revolving aboutthe pillar I) as an axis is a large bevel-gear wheel, H, provided with two slotted arms, H. These arms extend outwardly to the housings B, and revolve in a circular guide-ring, H2, bolted to said housings. Secured to the bed-plate A are three small is the pattern-form K. Said pattern-form is constructed with guideways or grooves 7c for the purpose hereinafter specified.

Upon the upper sides of the arms H and lengthwise of the same, guides 7i` are bolted, and in these guides slide the base-plates of the segmental arms L. Extending downward from said arms L, through the slots in arms H, and into the grooves or guideways of the formingpillars, I, and bolted to the tops of these pillars 5o pattern K are pins Z, carrying anti-friction 6o rollers. From this construction it will be seen that as the geanwheel H and the arms II revolve, the pins Z carrying anti-friction rollers will follow the guideway of pattern K, and the segmental arms L will slide toward or from the pillar D, according to the form ofthe pattern K. Sliding in guides formed in the segmental armsL are the segmental racks L. Said racks are provided on their outer edges with teeth, which register with worms M borne by shafts M. Said shafts are i ournaled near their lower ends in rocking bearings M2, and their upper ends are supported in eccentrically-movable journal-bearings m. rlhe latter move in eX- tensions m .of arms L, and are provided on Itheir upper extremities with hand-levers mi, by means of which `the worms M are thrown in orout of engagement with the racks L.

Attached. to the lower extremities of the shafts M are pinions in?, and these pinions gear with a segmental toothed rack, N, borne by slide-rod N working through openings in the housings B. Saidslide-rod is secured in any desired position by means of pin a passing transversely through the housings R. -The object of this rack is to actuate the pinions m, and, throughl the medium of the shaft M and worm M, to raise the segmental racks L.

Revolving upon spindles secured iu the rack L arethe fixed cylindrical rollers O, and revolving upon other pins or spindles, secured in the swinging plate or arm P, are the movable rollers O. This plate or arm P swings upon a pivot secured in the outer end of the rack L', and is fixed in its normalposition by 4a pin, p, passing through it andthe rack L. The object of this construction is to allow the with the metal plate operated upon when the rack L is lowered after. the plate has been iianged, and also to allow a new plate to be inserted after the one already operated upon has been removed.

The whole machine is actuated by a bevel gear wheel, R, meshing with the bevel-gear wheel H, and borne by the driving-shaft S. The latter has bearings in one of the pillars I and housings B.

rIhe operation of my machine is as follows: The pattern-forni K'hav'iug been bolted upon the pillars I, and the metal blank to be operated upon having been clamped upon the table E by means of the clamping device G F, the drivingvshaft S is put in motion. By this means the arms H are caused to revolve, and the pins Z, carrying anti-friction rollers ofthe segmental arms L, following the guideway of thepattern-forni K, causes the said arms L to slide toward or from the pillar D, and the rollers O O to describe a path similar in outline to the guideway of the pattern-form, and thereby flange the metal blank in like outline.

Contemporaneously with the above operation, the pinions m" ha' e at intervals engaged with, the segmental rack N, said segmental rack being moved from time to time in order to engage with said pinion, and the rollers O O have, through the medium ofthe shafts M, worms M `and rack L, been thereby turned upward until the flange upon the metal blank has attained the desired angle.

It will be understood that it' the pinions on catch or mesh with the rack N to the ex tent of three or four teeth, the amount of elevation of rack L necessary to the proper flanging of the plate is fully complied with, and this for the reason that the engine runs faster or slower, as the distance or amount of lfriction, &c., to be overcome is greater or less. rllhe langing ofthe metal blank being now completed, the pins p are removed from the swinging arms or plates I), in order to allow the rollers O' to swing outwardly. The worms M are then thrown out of engagement with ther racks L by turning the levers m attached to the eccentrieally-movable journal-bearings fm. Said racks Lare then lowered, the flanged plate removed and another inserted, the pins j) and the worms M reinstated, and themachine is ready to operate upon another bla-nk.

It will be seen that v in case a differentlyshaped pattern-form. is inserted the rack N must be moved inward or outward, as the case may be, to gear with the pinions mi. This is done by means of the slide-rod N, and said rack is fixed in the desired position by inserting the pin a in place.

It may be added that for purposes of convenienee the pattern-forms are usually made in two pieces, they being in that shape more readily and conveniently applied to and secured upon the pillars I.

Having thus described my invention, what I claim is l. In a Hanging-machine having revolving slotted arms, the combination of the guidepattern K" with the roller-bearing arms L, pro-v 3. The combination, with the fixed rollers O and the racks L', ofthe movable rollers O, pivoted plates P, and pins p, substantially as described,whereby the rollers O may be locked or swung out of place, for the purposes set forth.

4. The within-described machine for flanging metal plates of regular or irregular forni consisting, essentially, of housings B, pillar D, wheel H, having slotted arms H/, pillars I, guide-pattern K, arms L, toot-hed racks L, rank N, and clamp F, all provided with operating inechauism, and arranged in the manner and for the purposes set forth.
